Oh, and:
There's no such position as 'Principal Private Secretary'. The most senior civil servant is the Cabinet Secretary, and then each ministry is headed up by a Permanent Secretary. These are enormous executive positions with responsibility for thousands of staff, although ultimately answerable to the minister. Sir Humphrey is meant to represent a Perm Sec (later promoted to Cabinet Sec when your namesake became PM).
A PPS doesn't really have any kind of executive role per se. The main function is to act as the eyes and ears of a minister in Parliament, helping to pilot bills through the legislature and serving as a link between MPs and ministers. It's an unpaid job that ambitious MPs take on as a first step on the ladder. As for a 'junior minister', they don't ever have control over a department. Each government department is headed by a Secretary of State, who sits in the Cabinet and has overall responsibility for the whole department. Underneath the SoS will usually be 2 or 3 Ministers of State who have specific responsibility for certain portfolios within the department. With some of the larger ministries you also get Parliamentary Under-Secretaries, which are are actual ministerial posts (as opposed to a PPS), but much more junior than the others and responsible for comparatively insignificant portfolios.
Another thing: if a Parliamentary Private Secretary is the assistant to a Minister...I thought that a Principal Private Secretary (a civil servant) was the assistant to a Minister. So what does the PPS really do, as far as assisting the Minister, then?
And what about a "Junior Minister"? What do they do, run a junior Department?
